Outline
Intro
J.Tuzo Wilson observed that there are cracks in the continents similar to those on the ocean floor
the lithosphere has been broken into seperate sections called plates
The theory of Plate Motion
The theory of plate tectonics explains the formation,movement, and Subduction of Earth's plates
Plate Boundaries
Transform boundaries
Earthquakes occur frequently along these boundaries
Divergent boundaries
these boundaries mostly occur on the mid-ocean ridge and sometimes on land
Convergent boundaries
these boundaries occur on land
three types of convergent boundaries:continental crust and oceanic crust,Oceanic crust and oceanic crust,continental crust and continental crust
